Abstract
PCT No. PCT/EP96/01122 Sec. 371 Date Sep. 22, 1997 Sec. 102(e) Date Sep. 22, 1997 PCT Filed Mar. 15, 1996 PCT Pub. No. WO96/29311 PCT Pub. Date Sep. 26, 19964-Acylaminopiperidine N-oxides IaA1B1(Ia)where A1 is hydrogen or an organic radical and B1 is a radical IIa where R1-R4 are each C1-C4-alkyl and R1 and R2, on the one hand, and R3 and R4, on the other hand, may furthermore be bonded to form a 5-membered or 6-membered ring, R5 is H or C114 C4-alkyl and R6 is H or C1-C18-alkyl, are used for stabilizing organic materials against the harmful effect of free radicals, particularly in the distillation of monomers which undergo free radical polymerization, especially styrene.
